Chapter 14, Problem 102IAE
The two compounds whose structures are depicted here are isomers. When derived from petroplem, they always occur mixed together, meta-Xylene is used in aviation fuels and in the manufacture of days insecticides. The principal use of pare-xylene is in the manufacture of polyester resins and fibers (for example, Dacron). Comment on the effectiveness of fractional distillation as a method of separating these two xylenes. What other method(s) might be used to separate them?

The substance to be analyzed – is white, highly soluble in water salt. Flame
coloration test gives weakly-violet color. Interaction with concentrated sulfuric
acid leads to evolving of reddish-brown gas with pungent odour. Mixing of salt
water solution with chlorine water in presence of trichloromethane changes of
color of organic layer to orange.
What kind of substance is this?

Your employer hands you a heterogeneous mixture and asks you to isolate all of thehexane that you can from it. After some analysis, you determine that the mixture contains toluene, hexane,benzoic acid, water, sodium chloride, and sand. Explain how you would isolate pure hexane from thismixture. Remember that you can use techniques such as filtration, extractions, and acid/base chemistrythat we learned earlier in this course in addition to distillation. You may need to look up solubilities and/orboiling points online to solve this problem. You only need to isolate the hexane?
